I'll totally pretend to give you answers.
know the difference between FEELING helpless and BEING helpless.
So okay. You went on a trip and met a girl and felt titillated and infatuated for the first time in a while. Happens to literally every person in a long-term relationship. I flirt recklessly. My wife knows I do. She also knows I come home to her because a lot of it is situational. Infatuation is exploring the possibilities. Love is cherishing the realities. You may not be in love with Sarah but she's also not surprising you much anymore. Novelty is a hell of a drug.
And okay. Sarah accepted that she cares more about you than you care about her, and you, for some dumb goddamn reason, decided to keep her around as a fuckbuddy until AUGUST or some shit.
This is the only thing I'm going to give you a ration of shit for. You're in a shitty place. It sucks. I'm sorry. I'ma give you some pathways I promise but for a minute, sit there and feel bad for this. Because it's a shitty thing to do to another human being. "I don't feel that we have a future together but... let's keep rubbing our genitals together for another four months because we have nothing better to do." It's one thing if you're both at "eh" in the relationship but if you're already acknowledging that she's way more into you than you are into her, keeping her on the leash is fuckin' cruel, dude. And it's going to cause things to cascade one of three ways:
(1) She's going to muster up her self-esteem and drop you like a hot rock because who the fuck are you to string her along like that after you've both acknowledged that she's got feelings you can't reciprocate.
(2) She's going to take what she can get for as long as she can get it and try to win you over to her way of thinking HONESTLY. You've given her a deadline, you've given her an ultimatum, you've given her a way forward: how to win a guy in 120 days. And, as a bonus, she gets to bump uglies.
(3) She's going to take what she can get for as long as she can get it and try to win you over to her way of thinking BY ANY MEANS NECESSARY. You've given her a deadline, you've given her an ultimatum, you've given her a way forward: how to land your man in one easy step. And, as a bonus, you already had a pregnancy scare 5 weeks ago.
If I understand correctly, you have not been present at any doctor's appointments. You have her word that she's pregnant. If you believe her, that's plenty evidence enough. If you don't believe her, she wouldn't be the first person to fake a pregnancy in order to push a guy into marriage. It's happened to three of my friends, in fact. But don't focus on that. In the end it doesn't matter. Those three pathways are independent of pregnancy, real or feigned; the pregnancy is a complication but it does not affect the fundamental core of your relationship with Sarah.
Your relationship with your father is coloring your current situation way too much. Makes sense. Entirely natural. By all means analyze it, reflect on it, react to it, but then set it aside because the relationship that matters now is between you, your potential child, and the mother of that potential child. That's where a lot of the helplessness is coming from: you had no power over your father yet he still holds power over you. You have no power over this child yet this child holds power over you. Hold it up to the light, nod at it, then put it back in the drawer.
Your current reaction to Sarah has a lot to do with the fact that you thought you killed all responsibility to the relationship yet still managed to reap the benefits. Yet here she is, drowning you in responsibility and threatening to cut you off entirely from any benefits. She's making it clear that you are unnecessary to her future plans, much like you made it clear that she was unnecessary to yours. What was the word? "Paralyzed." All right. You're frozen. You can't move, you can't breathe, and you're freaking out. Hold it up to the light, nod at it, then put it back in the drawer.
You're all about abortion which leads me to believe that divorce doesn't offend your religious sensibilities. You're freaking out about your family's reaction to a kid out of wedlock. And you're fixated on this child's future alienation because you're going to have no input into their life. Yet the obvious solution - marry the girl - has been ruled out, out of hand, with no discussion whatsoever. Why is that?
Marry the girl. Now you've got a say in the kid's upbringing. Commit to not being a stranger. Get to know her family and friends. Commit to three more years in Germany, three more years of trying to see what kind of life you can build with Sarah. It's the first two years of a child's life that govern so much of their future and having two parents that love them under one roof where they feel safe and loved makes all the difference in the world.
If you're not into it within three years, part amicably. Support your child. Be a part of their life. Be anchored in her family. Be a relative that doesn't vanish. Be a father. You can be travel dad no problem. After you've front-loaded the commitment it'll be nearly impossible to shrug you off, particularly if you comport yourself like a gentleman. And fuckin' hell, you may discover that having something in common with Sarah, who is about to give over her body and time for the next two years to the life and well-being of your firstborn, makes her someone you can love more.
You might be surprised what happens when you extend the girl some trust and empathy. You might find she warms up into more of a person you want her to be. And, you might discover that she miscarries and you didn't have to blow up your life. Maybe you go through with the wedding, maybe you drop her like a hot rock and learn to never again string along a girl who likes you more than you like her.
Either way, your best move is to commit to a wedding and let it play out for better or worse. All the bullshit above aside, saying I'm going to do this means you're DOING something which breaks you free from paralysis. You're making a move, you're making a decision, you're acting towards your own future, and you're forcing the probability cascade to break down in your favor.
- You propose to the girl. She turns you down. You say you want to help. She turns you down. You try to be in the kid's life. She turns you down. You've done all you can, your father can't resent you completely, and the door is open to be a part later.
- You propose to the girl. She says yes. You get married, have a kid, stick it out as long as you can, and end up being Foreign Dad. By then you're more settled financially, you have a better idea what your future holds and you've influenced your child's future in an immeasurably positive way.
- You propose to the girl. She says yes. The pregnancy disappears. You walk away unscathed.
- You propose to the girl. She says yes. The pregnancy disappears. You find your feelings towards Sarah have changed. To be continued, for better or worse.
- You propose to the girl. She says yes. You have a family and live happily ever after.
Either way, when you've decided you no longer care for someone as much as they care for you, stop fucking them for both your sakes.
